Question

diference between direct and indirect speech?

Answer 1

direct speech is exactiy what someone said; the words are between inverted cammas 

indirect speech means the words we use to report what someone said...

Answer 2

Direct speech is when we report what someone says by repeating the exact words. In writing, we use inverted commas:
David: I have to talk to you about something. (original statement)
"I have to talk to you about something," said David. (direct speech)

Indirect speech (also called reported speech) is when we give the same meaning of what someone says without repeating the exact words. In this case, we do not use inverted commas and certain changes may be necessary:
David: I have to talk to you about something. (original statement)
David said he had to talk to me about something. (indirect speech)
